The Foxeer Echo antenna provides a useful amount of gain with a reasonably wide beam angle. Although it can't match a 5-turn helical for raw gain, the small size, robust construction and very good performance of this antenna makes it an ideal choice for those who want something with a high performance to size ratio.
Bottom line: I'll be using this instead of my 5-turn helical when flying miniquad proximity. It's a yes from me!
